According to a new poll, President Donald Trump stands before all his potential rivals for the 2020 election, despite Democrats insisting on pushing for impeachment.

The national poll, sponsored by USA Today and Suffolk University, showed that President Trump beat former Vice President Joe Biden by 3 percentage points, Vermont Sen. Bernie Sanders by 5 points, and Massachusetts Sen. Elizabeth Warren by 8 points.

The results indicate that the impeachment hearings have not undermined his core political support.

The survey – of 1,000 registered voters – was conducted Dec. 10-14 by landline and cell phone and has a margin of error of plus or minus 3 percentage points, according to USA Today.

President Trump stays strong

President Trump’s position remained remarkably stable, no matter who his opponent was. According to the poll, he was victorious with 45% against Warren, 44% against Biden and Sanders, and 43% against Buttigieg and Bloomberg.

However, there was more variation among the Democratic contenders when they faced President Trump. Biden received 41%, Sanders 39%, Warren 37%, Bloomberg 34% and Buttigieg 33%.

After the 2020 Democratic Party presidential primaries, it will be known which of these Democratic hopefuls will eventually become the candidate facing President Trump.

According to the poll, the president won among male voters, but all Democratic contenders had a majority or plurality of female voters.

The president also beat Democratic candidates in the 35-and-over age group, but lost among voters 18-34 years old.

The president faces no significant primary challenge from former Massachusetts Gov. Bill Weld or former Rep. Joe Walsh of Illinois, who have announced campaigns for the Republican presidential nomination. They each received just 2% among Republican voters; Trump was backed by 88%.

In November—according to an Emerson poll—support for the impeachment of President Donald Trump plummeted from 48% to 43%.

Along these lines, President Trump’s approval rating rose to 48% compared to 47% disapproval, as House Democrats move forward with the impeachment inquiry that seeks to remove him, according to the results of a new poll by Emerson Consulting.

Since the impeachment of President Donald Trump began, members of the Republican Party, analysts and civil society have criticized the severe irregularities in the process.

Some have even predicted that these contradictions will make it clear that the president did not commit any crime, it will reinforce his positive image and it will turn against the Democratic opposition that seeks to win the presidential elections in 2020.
