Call me a pessimist or a political cynic; but I figure there's not all that much by way of permanent changes Trump can instill in just four years.
We can hope that he gets to nominate another Supreme Court justice and that while the GOP controls both the House and Senate the conservatives can dominate the RINOs enough to get some things done for this nation to serve as a bulwark for when the leftist radicals of the Dem Party once again lie and bullshit their way back into power.
They WILL be back because history has taught us that Useful Idiot voters are an unending and ever renewing leftist resource in this nation. The insane and intellectually lazy and those lacking in an understanding of what keeps a Constitutional Republic strong and healthy ALWAYS fall again for the endless lies and false promises of the Political Left. Always.
