Hillary Clinton and Donald Trump are deadlocked nationally and are virtually tied in two battleground states, according to new polls released Monday.

In a head-to-head national contest, voters are split 46 percent to 46 percent between Clinton and Trump, according to a Bloomberg survey. Taking third-party candidates into account, Trump leads Clinton 43 percent to 41 percent.

The poll found that nearly half, 49 percent, expect Clinton to perform better at the first presidential debate on Monday night and 39 percent said the same about Trump.

Half of likely voters under the age of 35 said they back Clinton and 40 percent of them said they support Trump. Among likely female voters, Clinton leads Trump 52 percent to 39 percent.

More than two-thirds of likely voters said Trump should release his tax returns.

Three-quarters of likely voters said President Obama was born in the U.S., 11 percent said he wasn’t and 14 percent said they aren’t sure.

The poll surveyed 1,002 likely voters between Sept. 21 and 24 with a 3.1 percentage point margin of error.

A Quinnipiac University survey also shows the two candidates in a dead heat nationally, with 44 percent of likely voters supporting Clinton and 43 percent supporting Trump. Eight percent back Johnson and 2 percent support Stein. 

A CNN poll released Monday found the two nominees are virtually tied in Colorado and Pennsylvania.

In Colorado, 42 percent said they support Trump, 41 percent said they back Clinton, 13 percent support Libertarian Gary Johnson and 3 percent support Jill Stein.

In Pennsylvania, 45 percent back Clinton and 44 percent support Trump. Six percent said they support Johnson and 3 percent support Stein.

In two-way matchups, Clinton performs better in those two key states. She would lead Trump in Colorado 49 percent to 47 percent and would lead him in Pennsylvania 50 percent to 47 percent.

The poll surveyed 1,010 adults between Sept. 20 and 25 with 3.5 percentage point margin of error.

A Gallup poll released Monday found a third said Clinton is honest and trustworthy and 35 percent said the same about Trump.

The poll also found 69 percent said Clinton has the experience it takes to be president, while only 29 percent said the same about Trump. Half said Clinton is likeable, compared to 38 percent who said the same ofTrump.
