Republicans believe they can pick up the seat based on, among other indicators, the low popularity of President Barack Obama in West Virginia.
More than 50 people stood outside the Civic Center Saturday protesting the actions of the president and the administration. Large signs asked passersby to honk their cars if they wanted Obama impeached.
The administration's energy policies and the Affordable Care Act are not very popular in the state, and Democrats in West Virginia frequently try to distance themselves from the administration.
Like Manchin, Rahall, Capito and Rep. David McKinley, R-W.Va., Tennant has repeatedly denounced the actions of the U.S. Environmental Protection Agency since starting her campaign. She also recently sent out a statement in support of delaying the individual mandate in the Affordable Care Act for one year, a proposal pushed by Manchin.
The idea West Virginia Democrats asked Biden not to endorse Tennant doesn't hold any water though, said state party chairman Larry Puccio.
"We would never ask the vice president to say anything," Puccio said Sunday in a phone interview.
"We were just excited he took the time to be with us last night."
Puccio said he didn't get to listen to all of Biden's speech because he was helping orchestrate the event. But he enjoyed the parts he did get to see, and he's received plenty of positive feedback from people who attended.
Individual tickets cost $75, and people could sponsor a table of 10 for $1,200. A package that included two tickets to the dinner and to the reception before the event cost $1,000, and people paid $50 for the messages to Rockefeller that were displayed on large screens during the event.
Puccio said the final fundraising total won't be known until later in the week, after all the costs are determined and settled. But the party is able to contribute the maximum $1,000 allowed by law to political action committees devoted to electing Democrats in the state House and Senate.
"It may be the largest fundraiser we've ever had for the Democrat party itself," Puccio said.
