To coin a paraphrase: if Mitt Romney were to be videotaped throwing burning puppies at a homeless, Quadriplegic Iraq War veteran who was in church for his mother’s funeral, the Repubs would say “Yes, but the Democrats…”
If Barack Obama were to do likewise, the Dems would denounce and impeach him, THEN say “Yes, but the Republicans…”
An Independent would call the Police and Fire Departments (and the Humane Society), without all the poliitical finger-pointing crap.
Guess which one actually deals with the problems? (Hint: it ain’t the parties.)

We are told that Republicans are the party of the wealthy. Then it stands to reason that the more wealth there is in America the more the GOP can expand its voting base. In contrast, Democrats insist they are the party of the oppressed and impoverished…
Your syllogism fails – it is not the amount of wealth that expands a voter base, but rather the number of wealthy people. That number is not expanding: which is why the Republican base is not growing.
