State Sen. Marty Knollenberg (R-Troy, Birmingham, Bloomfield Hills, Rochester, Rochester Hills, Royal Oak) has told us he likes to make one-on-one phone calls to voters in his district to talk to them about their concerns. Word is that part of that strategy is extra steps to make personal appeals to female voters in Oakland County who may hold the key to which political party makes headway this election year. MIRS speculated that his campaign could be in trouble. Those personal phone calls to female voters are part of Knollenberg’s use of micro-targeting data against Democratic challenger Mallory McMorrow, where he makes personal phone calls to female voters, mentioning them by name and asking for their vote. His team is doing the traditional door knocking, of which they’ve hit 17,000 homes so far.
