Yes, without a second of hesitation.
If Trump starts a new party (or a new one pops up that is driven by other REAL conservatives) it will render the useless GOP an empty shell overnight, thereby returning us right back into a two party system. The big difference would be that it would really be two parties instead of a single Uniparty, which presently offers us no choices.
My check book is wide open for a MAGA America First party!!!
