President Trump is in a dead heat with four Democratic presidential candidates in GOP-leaning Texas, according to a new Emerson College poll.

The poll, released Monday, shows Trump in close races in hypothetical general election matchups in Texas with former Rep. Beto O'Rourke (D-Texas), former Vice President Joe Biden, Sen. Elizabeth Warren (D-Mass.) and Sen. Bernie Sanders (I-Vt.).

Biden has the best results against Trump, garnering the support of 50 percent of voters compared to Trump's 49 percent, the poll shows. O'Rourke's results are similar, with him and Trump each getting the support of 50 percent of voters in a hypothetical matchup.

Meanwhile, the poll shows Sanders losing by 2 percent and Warren trailing by 6 percent. Both of those differences are within the poll's margin of error.

Texas has long been in the eye of Democrats longing to make the state competitive. Winning the Lone Star State would greatly ease the chances of a Democrat winning the Electoral College, but no Democratic presidential candidate has won the state since Jimmy Carter in 1976.

O'Rourke's competitive run against Sen. Ted Cruz (R-Texas) in 2018 raised hopes for Democrats again, and some optimistically think 2020 could be the year.

The results are also important in the context of the Democratic primary race, where electability is an issue on Democratic minds. Biden has argued he is the candidate with the best change to defeat Trump in the general election.

The other candidates included in the poll - Sen. Kamala Harris (D-Calif.) and South Bend, Ind., Mayor Pete Buttigieg (D) - each trail Trump by 8 points in the state, outside of the margin of error.

The poll's results are based on interviews with 799 voters from April 25 to April 28. The poll has a margin of error of 3.4 percentage points.

O'Rourke predicted last month that he could win Texas if he earns the Democratic nomination for president.

"Yes, I think we can win Texas," O'Rourke said at the time. "I think we've proven we know how to campaign,"
