A new poll has been released showing the president leading potential GOP challenger John Kasich by a wide margin in Iowa. It would not even be close, with Trump winning 90 percent of voters.

According to The Daily Caller:

Former Vice President Joe Biden remains the best option Democrats have at beating President Donald Trump heading into the 2020 election, according to a poll of Iowa voters published Saturday.

Biden would beat Trump in a squeaker, pulling in 51 percent of the vote to the president’s 49 percent, Emerson College found in a survey. The poll’s results show other Democratic candidates have their work cut out for them in terms of name recognition.

Sens. Bernie Sanders of Vermont, Elizabeth Warren of Massachusetts, and Kamala Harris of California earned enough support in the survey, which was conducted Jan. 31 through Feb. 2, to fall within the research’s margin of error. Biden holds a nearly 20-point advantage over Warren in the Hawkeye State. The Democratic Iowa Caucus is a year away.

The poll also finds Trump would best  Ohio Gov. John Kasich in a head-to-head-match-up in Iowa: 90 percent to 10 percent. Former Starbucks CEO Howard Schultz’s potential candidacy would be a death knell for Warren, according to the poll, which surveyed 831 voters with a margin of error of plus or minus 3.4 percentage points.

Republicans, including Lindsey Graham, have made it known that they do worry about Biden’s chances against Trump. The former VP seems to be the most viable candidate so far.
