U.S. Sen. Mark Pryor says he raised $1.9 million for his re-election campaign in the first quarter of 2013, more than doubling the amount of money on hand for next year's race.
Republicans have targeted the two-term senator, believing he is vulnerable in a state that has seen the GOP take a number of statewide and congressional races since 2010.
According to the Democratic Party of Arkansas, which distributed Pryor's fundraising figures Thursday, the candidate has $3.4 million on hand.
Pryor is the only Democrat in Arkansas' congressional delegation. Democrats have steadily declined in Arkansas, hampered by President Barack Obama's unpopularity in the state and Republicans' consolidation of power across the South.
No Republican has yet entered the race against Pryor, whose father served as governor and U.S. senator.
