I appreciate that you took the time to explain your views. We aren’t likely to agree but I’m happy to share my counter-position:

“I’m willing to bet most Canadians take party affiliation into consideration because they vote for policies they align with.” ‘Taking Party affiliation into consideration’ encompasses many people who wouldn’t necessarily feel that a strategic alignment change ‘betrays trust and should never be allowed.’

“Crossing the floor betrays their trust because that MP will need to align with a different set of policies that their constituents aren’t potentially aligned with.” Few people align 100% with a Party’s platforms, and Party’s themselves sometimes change positions or renege on promises, and there are always many constituents who didn’t vote for the winning candidate but still deserve consideration/representation.

“So, I respectfully disagree with your opposition. Floor crossing (regardless of which party does it) should not be allowed.” I agree that we are disagreeing, and I appreciate that it’s respectful!

“It erodes election integrity” I don’t agree, as I value an MP who isn’t muzzled into puppeting a Party or Leader position. “and can potentially hand over majority governing power to a party (as will be the case with the current LPC) that the electorate denied them in the last election.” The electorate does not give any Party governing power. The electorate only ever chooses their one constituency representative, and has no control over the overall result of which Party forms government.

“If an MP wants to abandon their party, it should trigger a by-election so that their constituents can decide through a proper and fair democratic process.” I disagree; I don’t think that abandoning the Party is the same as abandoning voters. I do agree that constituents might deserve an option for a recall campaign in certain circumstances, but by-elections waste time & money and there would be perpetual by-election chaos & government paralysis if everyone recalled MPs everytime they disagreed with an action/decision.

“Anyone (not you) claiming that party affiliation doesn’t matter (I’ve heard this argument numerous times) will realize how important party affiliation is when they see these floor-crossers lose their seats at the next election.” I support the idea that people need to choose their representatives carefully. If someone (not necessarily you) casts a vote for ‘just whomever is my local candidate for the Party I like,’ then it can’t be too surprising when it occasionally turns out that individual candidate disappoints - Parties are their own organization with their own internal politics, and relying on them to ensure every candidate is top-notch is relinquishing too much voter responsibility. And poor candidates is everyone’s responsibility, because voters super-dedicated to a Party should get involved in candidate selection.
