President Trump leads presumptive Democratic presidential nominee Joe Biden by 2 points in a head-to-head matchup in Iowa, according to a poll released on Monday. 

Forty-eight percent of respondents in the Public Policy Polling survey threw their support behind Trump, while the former vice president trailed close behind at 46 percent support, well within the poll's margin of error. 

The poll from the left-leaning firm also showed Biden doing well with senior citizen voters in Iowa, coming in at 52 percent support, while Trump polled at 44 percent support with the group. 

The survey appears to predict a close race between Republicans and Democrats up and down the ballot in the Hawkeye State. 

Trump won the state by 9 points in 2016, but Democrats made inroads in the state in 2018, flipping two House seats. The Cook Political Report rates the races for Iowa's first, second and third House seats as "toss-ups" for the 2020 general election. 

The new Public Policy Polling survey also showed a tightening Senate race. Sen. Joni Ernst (R-Iowa) leads Democrat Theresa Greenfield by only 1 point in a hypothetical matchup. Ernst is likely to face Greenfield in November. The state's Democratic primary is slated for June 2. 

The Public Policy Polling survey was conducted on April 30 through May 1 among 1,222 Iowa voters. The margin of error is 2.8 percentage points.
