"Members of Congress can object to any state's electoral vote count, provided objection is presented in writing and is signed by at least one member of each house of Congress. An objection supported by at least one senator and one representative will be followed by the suspension of the joint session and by separate debates and votes in each House of Congress; after both Houses deliberate on the objection, the joint session is resumed. A state's certificate of vote can be rejected only if both Houses of Congress vote to accept the objection. In that case, the votes from the State in question are simply ignored. The votes of Arkansas and Louisiana were rejected in the presidential election of 1872."
So in layman's terms, Congress can reject any votes by "faithless electors" with a protest by a single member of Congress and a single Senator which triggers a majority vote in the House or Senate to sustain the objection. If the vote passes, the electoral votes in question are tossed.
If at that point no candidate has 270 electoral votes then that tosses the electoral college completely and kicks the election to a vote in the House where each state delegation votes as a block and Trump will win easily.
So under every scenario the left can devise, Trump will still win.
I don’t think Texans will take too kindly to their electoral votes being tossed due to the actions of that rogue elector from their state.
Better to replace that guy with someone that will keep their word and vote Trump.
Besides, that rogue elector signed the pledge.
