Incumbent Democrat Colin Allred has raised more than $1 million for his re-election bid as Republicans look for a candidate to wrestle back the Dallas-area seat once held by Pete Sessions.

For the second quarter of this year, Allred raised $575,000 for his campaign, with none coming from corporate political action committees. Allred has hauled in more than $1 million this year and has $950,000 in the bank, according to totals provided by his campaign Tuesday.

Allred, the former NFL player turned congressman, beat Sessions in one of the most critical contests in the nation. Sessions was chairman of the House Rules Committee and his ouster was a symbol of the Democratic takeover of the House.

But Republicans are expected to fight hard to regain District 32, the largely north and east suburban Dallas seat in what's considered a swing district.

On Wednesday former U.S. Rep. Allen West is expected to make an announcement on whether he'll challenge Allred. He's been teasing a video message on social media.

West, a retired Army colonel, represented a Florida district, but in 2012 lost a re-election bid to Democrat Patrick Murphy after running in a nearby district because of redistricting.

Even with that loss, he could be a formidable candidate. The conservative politician has built a strong national following and is a prolific fundraiser. In his 2012 unsuccessful re-election bid, he spent a whopping $18 million, according to the Center for Responsive Politics.

Records show West has about $940,000 in his House campaign account.

After moving to Dallas, West was executive director of the now defunct National Center for Policy Analysis.

Other Republicans are also considering or have been mentioned as possible contenders to challenge Allred. They include former state Rep. Dan Branch and state Rep. Morgan Meyer of University Park, as well as Sessions, who has $335,000 in his campaign account.

Allred, who grew up in District 32 and was a Hillcrest High School football standout, went through a tough Democratic primary before beating Sessions.

He benefited from a united Democratic Party front that included the groundbreaking Senate campaign of Beto O'Rourke, who came within 2.6 percent of beating incumbent Republican Ted Cruz and helped down-ballot Democrats like Allred rack up votes in Dallas County.

For the 2020 election, Allred will be boosted by a presidential election turnout, which typically favors Democrats.
