The left-leaning firm found 65 percent of the former Democratic presidential nominee's supporters say they are "very excited" to vote this fall, compared to 58 percent of those who supported Trump 

The poll also shows Democrats as having a lead on the generic congressional ballot. 

Forty-nine percent of those polled said they would vote for the Democratic candidate in this fall's midterms, while 41 percent said they would vote for the Republican candidate. 

The 2018 contest is expected to be a referendum on Trump's first two years in office, as well as on the performance of the GOP-controlled Congress. 

Trump and congressional Republicans scored their first major legislative victory in December after passing tax reform. 

Federal and congressional probes into alleged ties between the Trump campaign and Russia's election interference, however, have weighed heavily on Trump's first year in office. 

The White House is also publicly grappling with the fallout of the domestic abuse allegations against former staff secretary Rob Porter, who resigned on Feb. 7. 

The Public Policy Polling survey was conducted on Feb. 9-11 among 687 registered voters. The margin of error was 3.7 percent.
