2. Absolutely NOT in favor. What stops a President from receiving a bill, line-iteming out the funding for the bill, and then saying "oh well, guess we can't enforce this" then? The line-item veto is just too dangerous and can be used to selectively enforce laws way too easily.
3. A single piece of paper is ludicrous. Single-issue bills or laws, yes, but perhaps you could distill it down to "must provide a summative" or an abstract.
4. Congress USED to pass budgets. Then everything became an "emergency" around 2001-2002 or so (for some reason), and we haven't had a budget passed consistently since then. And I 100% guarantee you this is going to somehow become an issue again now that we have a D president, even though it hasn't been for the past four years.
5. You're right. Both sides are bad - but look for the side that isn't actively evil.
If your taxes were noticeably reduced by the current administration, your wife/husband makes a TON of money. The average household had a tax cut of under 1% of their tax bill. Only the top 20% of earners saw higher than 1.5%.
