INDIANAPOLIS — Former President George W. Bush is in Indiana to boost U.S. Senate candidate Todd Young, who became an unexpected underdog after Evan Bayh belatedly joined the race.

Bush was scheduled to attend two fundraisers Monday, in Indianapolis and Elkhart, as Young tries to close in on Bayh’s fundraising lead.

The Democratic former Indiana governor and U.S. senator entered the race in July after former U.S. Rep. Baron Hill dropped out. He had an almost nine-to-one cash advantage in June, with nearly $9.5 million in his campaign account.

Bush has kept a low profile since leaving office in 2009. Young says his presence underscores the importance of the race for Republicans.

Democrats hope to pick up at least four seats, which could allow them to take control of the chamber.
