With Alaska Sen. Lisa Murkowski (R) considering waging a third-party campaign, the DSCC could feel pressure to help Democratic nominee Scott McAdams, who could capitalize on Murkowski and Republican nominee Joe Miller splitting the GOP vote.Two open seats the DSCC has yet to jump into are Ohio, where former Rep. Rob Portman (R) appears favored, and New Hampshire, which is holding its primaries next week.However, spending in those states would force the committee out of other states where Democratic candidates could use the help. The DSCC has not reserved time in five states where the NRSC has: Florida, California, Illinois, Wisconsin and Nevada. Four of those five states are currently held by Democrats. The NRSC has $4 million in combined coordinated and independent expenditure funds reserved in Florida, $2 million in coordinated funds in California, $3.4 million in coordinated funds in Illinois, $500,000 in Wisconsin, and $700,000 in Nevada.The one state the DSCC has reserved time where the NRSC has not is Missouri, where Secretary of State Robin Carnahan represents one of the best chances for Democrats to pick up a GOP-held seat. In her race against Rep. Roy Blunt (R), the DSCC has already spent $1 million and has an additional $4 million reserved. A win there would help offset expected losses in other states and increase the number of Democratic-held seats the GOP needs to take back the majority.
