Today I got a prerecorded Ann Romney message asking me to support her husband. Earlier this week, prerecorded Mitt* called and played a clip of Santorum saying "It's Bullsh*t" Also got a call earlier this week from prerecorded Santorum asking for my vote.
None from the doc though :/
BTW, I live in Maryland and our primary is April 3. (but early voting has been this week) Hopefully the campaign is reaching out to voters like Romneytorum's campaigns seem to be doing so strongly.
*Which is a lot like the real Mitt, robotic.
