> I'm going to assume you're not in the USA.
Am not, but follow the politics there closely.
> Washington DC is over 70% Democrat
Am not talking about the actual place "Washington DC", am talking about it as a seat of power, the seat of government. The politicians in the House and Senate and their leanings.
> which is our left wing party
The Democratic Party is nowhere near "left-wing" by what most of the developed world understands that to mean. The Democratic Party has policies equivalent to the Conservative Party in Britain, (The Conservative Party is a right-wing party).
It is precisely because of the extremely right-wing ideology of most lawmakers in Washington that you have moved to such a position where the center-right, (Democrats), are called "left-wing" and the far-right, (Republicans), are refereed to as "center-right". Only in the USA. You don't have a viable left-wing party over there.
There's people like Bernie Sanders and AOC that are what I'd call center-left, but because how far right the acceptable debate in the USA has shifted, they're "socialists".
