Sometimes support can come from the most unlikeliest of places. CNBC's "Mad Money" host Jim Cramer tweeted today his father is one of the 750,000 registered voters in Pennsylvania who does not have a state-issued ID and won't be able to vote this November because of a voter ID law passed by state Republicans. 

Cramer tweeted: "I have a problem. My dad, a vet, won't be allowed to vote in Pa. because he does not drive, he is elderly, and can't prove his citizenship."

We reported earlier that the new law disenfranchises nearly one-fourth of senior citizens who have cast a ballot in every election in the past 50 years. 

This Thursday, the Pennsylvania Supreme Court will have a hearing on the constitutionality of this Voter ID law. TPM Muckraker reports the law is also "the subject of a Justice Department investigation evaluating whether the law is discriminatory under the Voting Rights Act."
