Double standards is the name of the game with all politicians/political parties.
In any case, the issue of illegal votes comes down to two possibilities: either our electoral system is damn near bulletproof and there's been less than 500 cases of voter fraud in the last 20 years or the "millions of illegal votes" claim is accurate and said voter fraud is undetectable. Of course, the logical catch on that is if it's undetectable, there's no way the person who originated the claim could know it to be fact -the extension of such being that if the claim is true, no amount of legislation can correct the issue.
