Senator Susan Collins proposes a compromise plan to cap income eligibility for Obamacare subsidies at $200,000 and eliminate zero-dollar premium packages, describing the cap as "very generous."Senate Republicans plan to block a proposed two-year extension of these subsidies, while Senate Minority Leader Chuck Schumer and Democrats push for a three-year extension to prevent premium hikes.The healthcare debate affects nearly 22 million Americans, with premiums expected to increase by 114% and over 2 million potentially losing insurance, especially in Florida where 4.7 million are enrolled in ACA plans.
