‘That’s a proper name and should be capitalized.’
No it’s not. By ‘democratic majority’ I mean having more votes than the opposition have, therefore it is not a proper noun and does not need to be capitalised.
As for your political point, I agree without reservation. :)
Thank you for clarifying the meaning of your terminology. Interpretation is nearly impossible given a single usage by a single writer when other usage by other writers varies especially in a secondary context without appropriate available parallel readings.
