In recent days, we have seen the results of important polls in the United States. US President Donald Trump believes all polls show his popularity to be fake! But many of Donald Trump's entourage and companions do not.

Here's a look at two new polls in the United States:

Q-poll: Support for Biden surges among Dems, Trump holding his own

The CT Mirror reported that a national Quinnipiac University poll released Monday shows former Vice President Joe Biden’s popularity has surged among Democrats since a similar survey was taken about a month ago.

Meanwhile, 32 percent of all American voters told Quinnipiac pollsters they would “definitely” vote for Trump if he is the Republican candidate in the 2020 presidential election, while 12 percent say they will consider voting for Trump.

But 54 percent of all American voters polled said they “definitely” will not vote for Trump, matching the “never Trump” total from a May 21 Quinnipiac University National Poll.

The new Quinnipiac poll showed Biden was the favored candidate to run for president among 34 percent of Democrats and “Democratic leaners” surveyed, followed by Sen. Elizabeth Warren, D-Mass., who won 15 percent of their support. Sen. Kamala Harris, D-Calif., came in third in the horse race poll at 12 percent, while Vermont Sen. Bernie Sanders collected 11 percent.

The latest poll shows Biden’s popularity rose 12 percent since Quinnipiac’s last survey, which had the former vice president favored by only 22 percent of respondents. That poll was taken shortly after the Democratic presidential debate. During those debates, Harris attacked Biden’s opposition in the 1970s to school busing to achieve the desegregation of public schools.

That attack seemed to help Harris, whose popularity surged in several polls, including the one Quinnipiac conducted a month ago. But support for Harris dropped by 8 percent in the latest university poll.

“In the blink of an eye, the post-debate surge for Sen. Kamala Harris fades and former Vice President Joseph Biden regains his footing among Democratic presidential contenders,” said Mary Snow, polling analyst for the Quinnipiac University Poll. Biden also has the best chance of beating Trump in the general election, said 51 percent of Democrats polled by Quinnipiac, with 10 percent for Sanders and 8 percent each for Harris and Warren.

But Snow said Warren seems to be the one to watch.

“While Biden and Sen. Kamala Harris have been riding a seesaw of support, Sen. Elizabeth Warren is holding steady in the support she’s seeing from Democrats and Democratic leaners and she remains the candidate seen as having the best policy ideas,” she said.

South Bend Mayor Peter Buttigieg was the favored candidate of 6 percent of those polled, while former Texas Rep. Beto O’Rourke drew 2 percent support.

One percent of those polled favored entrepreneur and Democratic presidential candidate Andrew Yang. The rest of the candidates in the Democratic candidates in the crowded field drew less than 1 percent support.

Quinnipiac University surveyed 1,306 voters nationwide from July 25 to July 28. The poll has a margin of error of plus or minus 3.4 percentage points, including the design effect. The survey included 579 Democrats and Democratic leaners with a margin of error of plus or minus 5.1 percentage points.

Poll: Biden holds 19-point lead over 2020 Democratic field, Warren places second

The Hill reported that Former Vice President Joe Biden widened his lead in the 2020 Democratic presidential primary to 19 points over second-placed Sen. Elizabeth Warren (D-Mass.), according to the latest Quinnipiac poll released Monday.

Biden widened his lead after the previous Quinnipiac Poll on July 2 showed Biden's lead over then second-placed candidate Sen. Kamala Harris (D-Calif.) had shrunk to just two points shortly after the first Democratic primary debate.

Warren placed second in the latest Quinnipiac poll with 15 percent support, up from third in the July 2 poll.

Warren was followed closely by Sen. Kamala Harris (D-Calif.), at third with 12 percent support, and Sen. Bernie Sanders (I-Vt.), at fourth with 11 percent support.

In the July 2 poll, Harris had placed second, with 20 percent support, after confronting Biden over the former vice president's policy opposition to federally mandated busing during desegregation, while Warren was at third, with 14 percent support.

South Bend, Ind., Mayor Pete Buttigieg (D) again placed fifth, polling at 6 percent. All other candidates in the crowded field are polling at 2 percent or less. The latest Quinnipiac poll was released just ahead of the second presidential primary debates set to take place over Tuesday and Wednesday. 

The Democrats will face-off again in two debates this week, 10 on Tuesday and 10 on Wednesday, in Detroit. Sanders and Warren will be on the same stage the first night, while Biden and Harris will again be on stage together at Wednesday’s debate. The poll was conducted from July 25 to 28 and surveyed 1,306 voters nationwide. There is a 3.4 percentage point margin of error.
