Mourdock was critical of Lugar on several fronts Tuesday, blasting the incumbent's support for the DREAM Act and the START treaty.
"We have raised close to three and a half million dollars, we have more than 10,000 signatures to get onto the ballot ... and we will continue to run our own campaign focused on the issues and the senator's record," said Lugar spokesperson Mark Helmke
, when asked for a comment on Mourdock's announcement.
"Lugar has opposed the Obama agenda on health care, on spending, on stimulus, on financial regulation," said Helmke, in response to Mourdock's comments regarding Lugar and Obama.
Now that Mourdock has made his bid official, state Sen. Mike Delph
's (R) intentions will be monitored even more closely. If Delph gets in the race, the potential for vote-splitting could work to Lugar's advantage. Mourdock said
he is in contact with Delph.
Mourdock also touted the support he has received from Indiana county chairs, releasing a long list
of names of those who are supporting him.
